Irish
subspecies
Jay
|
The Irish race of Jay Garrulus glandarius hibernicus appears generally darker and duller than both the British race G.g.rufitergum, and the Continental race G.g.glandarius. In comparison to the British race, hibernicus shows darker ear-coverts, sides of the head and mantle, while the underparts of the British race are slightly paler, especially towards the vent. The dark crown streaking on the British race tends to be thinner with broader white edges. This can give the crown a whiter appearance than seen on Irish birds. British Jays also show whiter throats and have a tendency to show a white area immediately below the eye which is rarely seen on birds of the Irish race.

The Continental race shows greyish to greyish-brown upperparts, while the underparts appear even paler than those of the British race. The darker Irish race therefore differs significantly from the Continental race. There have been no documented records of either the British or Continental race in Ireland.
